Statistical characterization of polycrystalline ferrite media

The classical field theory superposition principle, the central limit theorem, and the gyromagnetic equations of motion are invoked as a basis to formulate a quasi-static statistical model for polycrystalline ferrite media with Gaussian statistics. The use of this model to analyze small signal reversible rotational phenomena is illustrated. It is also demonstrated that this model and a previous microwave model given by the authors are maximum entropy models An analogy between the maximum entropy property of these models and the Gibbs thermodynamic equivalence for equilibrium and a state of maximum entropy is noted.
